摘　　要：研究了乙烯焦油用AlCl_3催化改质方法制备高可熔性中间相沥青的反应特性;求得了改质沥青和乙烯焦油沥青热缩聚反应速度常数和反应活化能等动力学参数,并对催化改质过程和中间相传化过程的组成和结构变化进行了分析。In this paper, reaction properties are studied on the highly soluble mesophase pitch formation from ethylene tar modified using A1C13 as a catalyst.The dynamic parameters like reaction Velocity constant and activation energy of thermal polycondensation of modified ethylene tar pitch and ethylene tar pitch were obtained. In addition, the processes of catalytic modification and mesophase transition were analyzed in terms of the composition and structural changes in the pitches.
